debug/111409 - don't generate COMDAT macro sections for split DWARF
Split DWARF files aren't processed by the linker, so DW_MACRO_import
offsets aren't relocated and the .debug_macro.dwo sections aren't
deduplicated and merged. There's no clear way for this to work for
split DWARF, so disable it.
gcc/ChangeLog:
PR debug/111409
* dwarf2out.cc (output_macinfo): Don't call optimize_macinfo_range if
dwarf_split_debug_info.
gcc/testsuite/ChangeLog:
PR debug/111409
* gcc.dg/pr111409.c: New test.
